 Want to experiment with TInCuP before installing? Use our Compiler Explorer examples:
 
-- Compiler flags used: `-std=c++20 -O2 -DTINCUP_DIAGNOSTIC_LEVEL=3`
+- Compiler flags used: `-std=c++20 -Wno-c++26-extensions -O2 -DTINCUP_DIAGNOSTIC_LEVEL=3 -DCOMPILER_EXPLORER`

 * [Bool Dispatch](https://godbolt.org/z/K1xcqqPad)
-* Enhanced Error Diagnostics:
-  - [Forgetting to dereference](https://godbolt.org/z/TKbvz8fMd)
 
-These examples demonstrate that TInCuP:
-- ✅ Works with all major compilers (GCC, Clang, MSVC)
-- ✅ Produces optimal assembly (check the "Add New → Opt Output" panel)
-- ✅ Provides clear error messages
